Watch oiler



W. T. LINDER Oct. 20, 1953 WATCH OILER Filed June 22, 1950 IN VENTOR ATTORNEY Patented Oct. 20, 1953 UNITED STATES" PATENT OFFICE My invention relates to an oiler for lubricating watches and other small work.

An important object of the invention is to provide an oiler of the above mentioned character,

which feeds the oil by capillary action and has an end suiiiciently small to enter the oil cup of jewel bearings of small bracelet watches.

A further object of the invention is to provide an oiler of the above mentioned character, having a reservoir for holding a small amount of oil, and the parts which contact with the oil being separable from the handle and from each other so that they may be cleaned in a watch cleaning machine.

A further object of the invention is to provide an oiler of the above mentioned character which will protect the oil from the action of light and which is of simplified construction.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this application and in which like numerals are employed to designate like parts throughout same,

Figure 1 is a side elevation, actual size, of a watch oiler embodying my invention,

Figure 2 is a central vertical longitudinal section, upon a greatly enlarged scale, through the oiler, the handle being broken away,

Figure 3 is a transverse section taken on line 3-3 of Figure 2,

Figure 4 is a transverse section taken on line 4-4 of Figure 2, and,

Figure 5 is a central longitudinal section through a modified form of the capillary tube, and reservoir, upon an enlarged scale, the reservoir being partly broken away.

In the drawings, which illustrates a preferred embodiment of my invention, the numeral l3 designates a cylindrical reservoir, having its forward end covered by a tapered head II, formed integral therewith. The rear end of the reservoir is open and has a reduced portion [2, forming a shoulder [3. This reservoir is preferably formed of stainless steel or any other metal or material which will properly hold the oil and will not corrode. The reservoir in has its periphery milled or roughened, as shown at H.

The numeral I5 designates a tubular coupling, which is preferably formed of stainless steel although it may be formed of nickel, brass or other materials. The tubular coupling has a cylindrical bore IE to receive the reduced portion l2 of the reservoir l0 and this reduced portion has a close sliding fit in the bore 16, to form a dust-proof joint. The coupling has its free end provided with longitudinal slots IT, whereby the free end of the coupling is somewhat resilient and the resilient free end may be bent inwardly slightly. The free end of the reduced portion I2 is beveled or inclined at l2, so that the reduced portion may be readily led into the free end of the coupling I5. The reduced portion 12 has suflicient frictional engagement with the coupling so that it remains within the coupling during the use of the implement but the reservoir and cou pling may be readily separated when they are to be introduced into the watch cleaning machine. The coupling [5 is provided upon its periphery with a milled portion l5. The coupling [5 has a stem l8 formed integral therewith, and this stem has screw-threads I9 to engage within the screwthreaded axial opening 29, of a handle 2|. The handle 2| may be formed of plastic material or the like. The coupling is detachably secured to the handle and is separated from the handle when the oil holding parts are to be cleaned.

The tapered head H is provided with a central axial opening 22, receiving a capillary tube 23. The tube is preferably permanently secured to the head I l and is held within the opening 22 by a press-fit or by any other means. The numeral 24 designates a capillary tube of smaller diameter than the tube 23 and adapted for insertion within the forward end of the capillary tube 23. The tube 24 preferably has a press-fit 7 within the tube 23 and is preferably permanently secured thereto.

The first form of oiler, Figures 1 to 4 inclusive, is adapted for use with heavy watch oil, and for this reason the capillary tube 23 has a somewhat larger diameter than would be needed for the handling of light watch oil. The inside diameter of the tube 23 is .35 mm. and the exterior diameter of the tube may be .63 mm. The capillary tube 23 has an exterior diameter too large to enter the oil cups of the jewel bearings of bracelet watches. To overcome this difiiculty, I provide the smaller diameter tube 24, which may be read- 11y inserted into such oil cups. The smaller diameter capillary tube 24 has an inside diameter of .23 mm. and an outside diameter of the proper size to fit snugly within the bore of the tube 23. In Figure 5, I have shown a modification of the oiler, wherein a tube 23' is used instead of the two tubes 23 and 24, and the capillary tube 23' has the overall length of the tubes 23 and 24. The tube 23' has the same small exterior diameter as the tube 24 and an inside diameter 2,656,070 3 4 of .23 mm. The tube 23 is sufficiently small to coupling I5 is separated from the handle and enter the oil cups of the jeweled bearings in the reservoir I separated from the tubular coubracelet watches. However, the bore of the tube pling 15. The separated tubular coupling and 23' is too fine for the handling of most heavy reservoir l0 carrying the capillary tubes 23' and oils and this capillary tube 23' is more suitable 24 are now placed in a conventional watch cleanfor handling light watch oils. The tube 23 is ing machine, and they are subjected to the action secured to the head I I, by being inserted into the of the cleaning fluid of the machine. This cleanopening 22, and this opening is formed of a suiting fluid will thoroughly clean the interior of able size to receive the tube 23 and form a pressthe parts I5, 10, 23 and 24.
